wherein R.sup.A is saturated, straight, branched or cyclic alkyl containing 1 to 14 carbon atoms, and R.sup.A is optionally substituted with 1 to 3 hydroxyl groups; and wherein R.sup.C is a residue of 2,2,4-trimethyl-1,3-pentanediol and R.sup.C can optionally be substituted with a group of the structure OC(O)R.sup.E wherein R.sup.E is straight, cyclic or branched alkyl containing 1 to 14 carbon atoms which is optionally substituted with a hydroxyl group, wherein the compounds of formula (1) contain 7 to 16 carbon atoms and are substituted with a total of 1 to 3 hydroxyl groups; and
(b) 5-90 wt. % of one or more quaternary ammonium cationic agents.

2. A homogeneous liquid cationic composition comprising 2,2,4-trimethyl-1,3-pentanediol isobutyrate monoester or diester and 5-90 wt. % of one or more quaternary ammonium cationic agents.

3. A homogeneous liquid cationic composition comprising hydroxypivalyl hydroxypivalate and 5-90 wt. % of one or more quaternary ammonium cationic agents.

4. A homogeneous liquid cationic composition comprising:

(a) a coupling agent selected from the group consisting of compounds of the formula (1)
wherein R.sup.A is saturated, straight, branched or cyclic alkyl containing 1 to 14 carbon atoms, and R.sup.A is optionally substituted with 1 to 3 hydroxyl groups; and wherein R.sup.C is a residue of 2,2,4-trimethyl-1,3-pentane diol and R.sup.C can optionally be substituted with a group of the structure OC(O)R.sup.E wherein R.sup.E is straight, cyclic or branched alkyl containing 1 to 14 carbon atoms which is optionally substituted with a hydroxyl group, wherein the compounds of formula (1) contain 7 to 16 carbon atoms and are substituted with a total of 1 to 3 hydroxyl groups;
(b) a compound of the formula (2)
wherein R.sup.T is saturated, straight, branched or cyclic alkylene containing 4 to 12 carbon atoms, and each X is ethylene, straight or branched propylene, or straight or branched butylene;
x is 0 to 40;
each Y is ethylene, straight or branched propylene, or straight or branched
y is 0 to 40; wherein the sum of (x+y) is 1 to 10; and
(c) 5-90 wt. % of one or more quaternary ammonium cationic agents.

5. The composition in accordance with claim 4, wherein at least one of component (a) includes 2,2,4-trimethyl-1,3-pentane diol and component (b) includes 2-ethylhexyl-1,3diol.

6. The composition in accordance with claim 4 wherein component (b) contains at least one compound of the formula (2) wherein R.sup.T is the residue of 2,2,4-trimethyl-1,3-pentanediol.
